激光淬火在提高金屬表面的耐磨性、耐腐蝕性、耐疲勞性和沖擊性等方面，都可以取得明顯的效果；且激光淬火無污染，屬于局部表面處理， 壓力小、變形小，具有廣闊的應(yīng)用前景。
Laser quenching can improve the wear resistance, corrosion resistance, fatigue resistance and impact resistance of metal surface. And laser quenching pollution-free, belongs to local surface treatment, small pressure, small deformation, has broad application prospects.
